The ground response curve (GRC) depicts the relationship between support reaction force and ground displacement, which improves the understanding of ground-support interaction and provides important references to the tunnel design. However, it is dif

A fire can pose a significant threat to a building’s occupants and leads to property damage. The burning characteristics usually determine the severity of the accident. Environments in high-altitude areas feature low oxygen content and ambient pres

Abstract In this paper, a family of the weighted polymer networks is introduced depending on the number of copies f and a weight factor r. The topological properties of weighted polymer networks can be completely analytically characterized in terms o

The Deformation Reserved (DR) method and the Pilot Heading (PH) method are two commonly used stress release methods in the construction of weak rock tunnel under high geostress. The ground pressure exerted on the support would be reduced to a certain

The rational use of natural wind in extra-long tunnels for feedforward operation ventilation control can dramatically reduce tunnel operation costs. However, traditional tunnel natural wind calculation theory lacks a prediction function. This paper p

Many previous studies have focused on air quality in road tunnels, which is a major concern for ventilation design. However, few researchers have investigated the air quality in tunnels in high-altitude areas. The ambient environment in high-altitude

To study the characteristics of driver fatigue and effect of a special light belt to relieve driver fatigue in an extra-long highway tunnel, real-road driving tests were conducted in the Yanglin extra-long tunnel. The tests were conducted separately
